Depends on what Rules your running....and type of vehicle....
Acid Bath....usually about $500-1000 depending on whos doing the work...and who's stripping the vehicle...

Seam Stitch weld....You might consider learning to do it yourself and save some cash...but most of it is all labor....so whatever the going rate is for a decent welding shop...

roll cage.....TOTALLY depends on what class/series/type of racing your wanting to do...and depends on materials you want to use....Chromoly or mild steel...how many points do you need...door bars....roof bars....bolted in or welded in...or both...if'n its rally...you can get a FIA legal cage from Europe thats about $1500 plus the labor to put it in....It also depends on wall thickness, mandrel or crush bent...I think Ralli-spec does cages...in mild steel for around $2000.. chromoly is about $4500 or so .I think... Chromoly is lighter than mild steel..so you need less wall thickness to achieve the required strength...so if weight is a consideration...maybe chromoly is a better way to go...

Before you get to involved...with whatever racing your going to attempt....you need to get a rule book for that particular venue.....and then call around to see who the premier builder for that type car...they will know what is legal and what isn't for your application....chances are they already know the rules...and can be better advised to give you estimate...

EX:..you call the 'local' drag shop that specializes in 1/4 mile cars....your chances to get a quality cage built for Rally have suddenly gone down the crapper because they might give you great price but know nothing of the rules your trying to follow...

If your trying to do this in a street car...for rigidy....Be careful..as your new found rigidy could bust your noggin...oh..and Safety is the most important thing...Don't Skimp...Ask yourself "How much is my noggin worth???"...get what you can afford but make sure its safe...

Go to the kind of races-rallies-track days you want to do.

Talk to racers there, THEY know the real answers to your questions.

Work up a budget for what you want based on above feedback.

Then TRIPLE your estimate, plus leave a couple thou for "incidentals."

Maybe this figure will end up being close...and even then only for the first couple of events!

This is why it's ALWAYS cheaper to buy a built-up car instead of doing your own. Starting out, you don't know what you don't know yet...unless you literally have $$$ to burn, you are totally absolutely 100% nutz to build your own car and not buy a built one.

But hey, it's your $$$...

First it depends on the class,

But general rulle of thumb roll cage install depending is approx 2500

Seam welding is approx 2k (you can do it yourself but becareful you can warp the car or blow holes through the floor.

The better the prep the better the weld.

Call us if you want more info.
